FPGAs have advantage over ASICs such as rapid prototyping, in circuit programmability, lower NRE costs and results in more economical designs. In conventional pipelining technique, the operating frequency is increased by dividing the combinational logic into number of stages and registers are introduced between the stages. All the registers are fed with a global clock. This improves the speed o...

INTRODUCTION Multiple sclerosis is an inflammatory disease involving the occurrence of demyelinating, chronic neurodegenerative lesions in the central nervous system. We studied vestibular evoked myogenic potentials (VEMPs) in this pathology, to allow us to evaluate the saccule, inferior vestibular nerve and vestibular-spinal pathway non-invasively. METHODS There were 23 patients diagnosed wi...

The effects of anti-epileptic drugs (AEDs) on brainstem auditory evoked potentials (BAEPs) were studied on 32 female patients of epilepsy and 10 age-matched normal healthy females (NS). The patients were divided into 6 groups, those not receiving medication (drug free, DF) and those receiving AEDs: Phenytoin (PHT), Carbamazepine (CBZ), Phenobarbital (PB), a combination of PHT and PB and a combi...

This paper presents data concerning auditory evoked responses in the middle latency range (wave Pam/Pa) and slow latency range (wave N1m/N1) recorded from 12 subjects. It is the first group study to report multi-channel data of both MEG and EEG recordings from the human auditory cortex. The experimental procedure involved potential and current density topographical brain mapping as well as magn...

Aims: Autism is a pervasive developmental disorder. Deficit in sensory functions is one of the characteristics of people with autism, and usually these people show abnormality in processing and correct interpretation of auditory information. Also people with Autism show problems in communicating with others. This review article deals with the accurate understanding of Auditory processing skills...

meniere’s disease is the disorder of inner ear characterized by vertigo, tinnitus and sensorineural hearing loss. the vestibular evoked myogenic potential (vemp) test could be useful in the analysis of saccular function, and diagnosis of meniere’s disease. in this study, we’ve analyzed the saccular function, using vemp test in different groups of meniere’s disease. patients were categorized as ...

while most tinnitus cases have some degree of hearing impairment, a small percent of the patients admitted to ear, nose and throat clinics or hearing evaluation centers are those who complain of tinnitus despite having normal hearing thresholds. present study was performed in order to better understanding of the probable causes of tinnitus and to investigate possible changes in the cochlear and...

Murid γ-herpesvirus-4 (MuHV-4) promotes polyclonal B cell activation and establishes latency in memory B cells via unclear mechanisms. We aimed at exploring whether B cell receptor specificity plays a role in B cell susceptibility to viral latency and how this is related to B cell activation. We first observed that MuHV-4-specific B cells represent a minority of the latent population, and to be...

INTRODUCTION The natural aging process may result in morphological changes in the vestibular system and in the afferent neural pathway, including loss of hair cells, decreased numbers of vestibular nerve cells, and loss of neurons in the vestibular nucleus. Thus, with advancing age, there should be a decrease in amplitudes and an increase in latencies of the vestibular evoked myogenic potential...

Introduction The effects of increasing stimulus repetition rate on the ABR using click stimuli have been investigated in normal and hearing impaired subjects with neurologic abnormality but there is limited study effect chirp stimuli. present aims to compare evoked auditory brainstem responses reference changes latency peaks, interaural differences interwave intervals as a function those respon...
